NPK Bulk Blending Fertilizer Production Line
Introduction of BB Fertilizer Production Line
BB (bulk blend) fertilizer is a versatile compound fertilizer
consisting of granular N, P, and K materials. It allows flexible
formulation tailored to different soils, providing concentrated,
balanced nutrition that saves time and labor while significantly
boosting crop yields. Typical raw materials include ammonium
phosphates, superphosphate, potassium chloride, ammonium nitrate,
urea, and ammonium sulfate.
